What is your idle vaccume? Mine is only like 5 inhg. Also does your car idle really rough? My car almost stals sometimes when I am driving and let off the gas. Will this get better as the ecu learns the cams? I lowered my fuel pressure a little bit too. I heard that would help. Any suggestions to get her to idle better?

Any good cams with overlap have low vacuum. Mine do as well. What FPR are you running? The problem I've seen with lowering your idle fuel pressure is the vacuum at idle is closer to the vacuum at WOT, so you have also lowered your WOT fuel pressure as well.

The best tool I have to help tune idle is the S-AFC, modifyign the map signal tricks the ECU is delivering less fuel, which is needed ecause the ECU dumps fuel in with the lower vacuum reading due to the cams. Another trick you can use is to adjust the throttle plate stop on your TB and let more air in, helping to offset the bog amounts of fuel the ECU dumps in.

i got stage 2 crower cams and i can't wait to put them in!!! Hoping for big power gains.

OK I am running the 8 injector setup. SO my primary injectors are stock size. All I have is the 1 to 1 FPR. So I can only adjust the overall fuel pressure. I really dot want to buy an safc if I dont have to. Maybe I will bump up the idle. I will try that. my fp is at like 42-45 lbs.

Just bought Crower stage 2 cams, I have not installed them yet. Any helpful hints?

Have fun with your idle!

I am having the exact same problems after installing my crower stage 2's, and posted the exact same question a few months ago. And the problem still exists. I've finally fixed the timing marks on the AEM cam gears, but I have yet to try adjusting them at all for fear that I will screw something up. Hopefully I will be ordering an SAFC and 60mm TB next week along with my new flexplate, tranny cooler, and shift kit.
Now I just have to figure out how to set the damn SAFC and cam gears together.x(

Best way is with a datalogger and watch your fuel trims to set idle and low throttle settings.

Cam with overlap will create a tuning issue, there's no way around it. Best bet for not doing it with an S-AFC is to adjust the throtle plate stop out and get more air in.
